Tactile Fixations: A Behavioral Marker on How People with Visual Impairments Explore Raised-line Graphics

“…When exploring a raised-line graphic, cognitive exploration strategies may differ across users [1] [21] [25] [46]. The basic purpose of the cognitive exploration strategies is to find out what information is encoded in the graphic and to elaborate and memorize a functional mental representation of the graphic [22].…”

Tactile cartography in the digital age: A review and research agenda

“…Here, I draw a line between participatory research and participatory design -while the terms are sometimes used interchangeably, the former will refer here to decisions concerning research protocol, while the latter will concern the design of an artefact, but not necessarily experiments and interviews, and so on (see Albouys-Perrois et al, 2018, for a brief overview of literature on adapting participatory design practices to people who are B/VI). In drawing this distinction, participatory design is more closely aligned with other progressive design approaches such as codesign (Coughlan et al, 2020;Yusim, 2019), user-centered design (Bardot et al, 2017;Rassmus-Gröhn, 2008) or inclusive design (Chamberlain and Dieng, 2011;de Almeida, 2014). This is not simply a rhetorical move, as important questions have been raised about the degree to which B/VI participants actually have any control over the research protocol and how they are represented in the final research output.…”

Vibrotactile cues for conveying directional information during blind exploration of digital graphics

“…Ces dernières années, de nombreuses études ont montré qu'il était possible de perme!re aux PDV d'accéder aux informations graphiques numériques au moyen de techniques d'interaction haptiques et/ou sonores, ce qui permet de profiter des avantages des informations numériques (facilement modifiables [10] et interactives [4]). Parmi ces études, plusieurs travaux ont été menés pour concevoir des techniques d'interaction perme!ant de rendre les graphiques numériques accessibles [4], mais aussi pour étudier les stratégies utilisées pour explorer les graphiques physiques [5]. Les découvertes ont montré qu'il existe notamment des indices tactiles particulièrement importants lors de l'exploration de graphiques physiques.…”
